Interface ImageAddressSpace

All Known Implementing Classes:
ImageAddressSpace, J9DDRImageAddressSpace, JCImageAddressSpace
public interface ImageAddressSpace

Represents a single address space within the image.

On some operating systems (e.g. z/OS), there can be more than one address space per core file and more than one process per address space.

  • Method Details

    • getCurrentProcess

      ImageProcess getCurrentProcess()
      Get the process within this address space that caused the image to be created.
      Returns:
      the process within this address space which caused the image to be created, if any. Return null if no individual process triggered the creation of the image.

    • getProcesses

      Iterator getProcesses()
      Get the set of processes within the address space.
      Returns:
      an iterator which provides all of the processes within a given address space.

    • getByteOrder

      ByteOrder getByteOrder()
      Return the byte order of this address space.
      Returns:
      the byte order of this address space

    • getPointer

      ImagePointer getPointer(long address)
      A factory method for creating pointers into this address space.
      Parameters:
      address - the address to point to.
      Returns:
      an ImagePointer for the specified address.

    • getImageSections

      Iterator getImageSections()
      Get the raw memory in the address space.
      Returns:
      An iterator of all the ImageSections in the address. Their union will be the total process address space.

    • getID

      String getID() throws DataUnavailable, CorruptDataException
      Gets the system wide identifier for the address space
      Returns:
      address space ID
      Throws:
      DataUnavailable
